Zoetis Vetscan Imagyst Allegedly Misclassified Dog's Cancerous Tumor, Leading to Second Surgery and Death
In October 2025, Columbia Veterinary Hospital in The Dalles, Oregon reportedly used Zoetis's Vetscan Imagyst AI to analyze a rapidly growing neck mass in an 11-year-old Belgian Tervuren. The system allegedly classified the mass as inflammatory, while a later biopsy found aggressive cancer. The hospital alleges the first surgery failed to remove all cancer, requiring a second operation; the dog died from complications. Zoetis allegedly later apologized and said similar incidents had occurred.
